`Application september 2, 192.1; serial No. 564x810 3 Claims.

1""This invention relatesto controlling mechanisrn 'for windshields Grand is a structural Vimprovement upon Fthe idea disclosed and broadly claimed inthe Beitman'application, SerialNa 386,780,1iled August 19,' 1929.V 1

' The object of the presentinvention is to pro-v vide a,clampingfor` securing mechanism for adjusting the windshield in any desired position which is positive in action and does not rely upon friction.

Another object of the invention is to provide van inexpensive assemblagewhich may be applied to windshields of various kinds and which overcomes the possibility of slippage when traversing rough roads at high speeds.

A still further object of the invention is to provide means for enclosing the various controlling apparatus from View and so constructed that the operator with one hand, while driving the car with the other, may adjust the shield and lock it without diiculty.

Other objects of the invention will be apparent from a reading of the following specication in conjunctionwith the drawings attached hereto and forming a part hereof in which Fig. l represents an elevational view of a portion of the shield;

Fig, 2 represents a longitudinal sectional View taken on line 2--2 of Fig. 1 showing different `'positions of adjustment of the shield;

Fig. 3 is a detail sectional view of the bracket and rack taken on line 3-3 of Fig. 2;

Fig. 4 is a detail cross sectional View on line i-li of Fig. 2;

Fig. 5 is a detail sectional view on line 5--5 of Fig. 2;

Fig. 6 is a side elevation of a modified form of clamping mechanism; and

Fig. '7 is a sectional view of the structure shown in Fig 6. Y

Referring now more specifically to thedrawings, I represents a windshield of the modern type adapted for outward movement and hinged of the rotatable locking tube II.

Along one or both of the vertical sides of the windshield isa channel shaped housing or bracket I2 in which -isreceived the locking tube II aforesaid. lThelockingA tube has a lateral opening slot extending vertically thereof, and the bracket I2 also has a 'lateral opening vertically extending .slot Aas shown particularly in Fig.4. v

The lower end of the brace arm 4 is provided with a rivet I3 having a ball or spherical end I and rotatably secured to the bracing 10 arm as at I5. The ball snugly ts within the confines of the rotatable lock tube and the shank of the rivetA extends through the slots provided by the tube and bythe bracket housing respectively. The locking tube at one edge of the slot 15 has a series of teeth I6 as clearly shown in Fig. 3.

The operation of the device is as follows: When it is desired to adjust the shield, the handle 6 is rotated to therebyl move the pushr rod 8 and 20 impart a corresponding rotative movement to the locking tube II until theslot thereof alines with the slot of the bracket housing I2 and the shank of the rivet I3 is disengaged from the rack teeth I 6. When in that position, the shield can be moved up and down with the brace arm and the connecting rivet I3 slides freelyY within the locking tube. When the desired open position is obtained, the said handle is pushed down which causes a rotation of the locking tube II until it tightly engages the rivet` with one* of the teeth provided by the rack on the said locking tube. In that position the shield is positively clamped.

It will be observed that the spherical end I4 35` permits the free rocking movement of the' tube I I to and from its engagement with the rivet I3.

In Figs. 6 and 7 there is illustrated a modified form of control structure which includes a channel shaped housing or bracket I9 within which 40 is positioned the locking tube 2|. The housing and tube are provided with longitudinally eX- tending slots, as described in connection with the Apreceding structure, but in this modification, the

teeth I8` are formed in an edge of the slot in the 45 housing or bracket I9. The element I'I is formed with a ball shaped head which snugly iits within the bore or the locking tube 2| and has its shank extending through the slots of the two telescopically arranged members I9 and 2|. l 1

During the operation of this modified structure, movement of the handle 6 Will cause reciprocation of the rod 8 for rotating the tube 2I. The movement of the tube will cause a corresponding movement of the element I1 to shift 55 the shank of the rivet into or out of the notches formed by the teeth I8 in the housing or bracket There is of course, as shown in Fig. 7, a loose connection between the end of the so-called rivet and the brace arm so that lateral movement of the rivet is permitted.

Whatrlrclaim as new is: v, Y

1. In` combination,y a Windshield frame, a windshield swingingly mounted therein, a bracket housing secured to the frame, a locking tube lo.-

cated within the housing, bracing means pivoted at one end to the Windshield frame and being provided at the other end with a rocking lever having a spherical head located Within the locking tube, means for rotating the locking tube to bind the rocking lever and restrain it from longitudinal sliding movementrelative to the shield When the shield has been adjusted to its desired position.

2. ln' combination, a windshield frame, a Windshield swingingly mounted therein, a channel housing secured to said windshield and having a slot extending laterally thereof, a locking tube located Within 'the channel and being provided vvith a slot, a rocking arm universally mounted Within the tube for sliding movement during the adjustment of the shield, bracing means secured to the Windshield frame at one end and being connected with said rocking arm at the other end, and means for rotating said tube to laterally move said rocking arm into binding engagement to restrain its movement when the shield has reached its adjusted position.

3. `In combination, a Windshield Vframe, a Windshield pivotally mounted inthe frame, a bracing element pivotally connected to the frame, and a.

, sildable, interlocking connection between the bracing element and the windshield, said slidable interlocking connection comprising a housing member having a longitudinal slot secured to the Windshield, a locking tube member having a longitudinal slotV rotatably received Within said housing member, one edge of said longitudinal slot in one of said members having a series of teeth formed therein, and a pin carried by the bracing element and having a large head received Within the bore of the locking tube with the shank of the pin received Within said slots and adapted to engage said teeth to prevent movement of the pin longitudinally of the locking tube when the tube is rotated relative tothe housing.
